The 2.7 Ecoboost in the F150 has some impressive gains when applying just a tune (Stage 1). The second vehicle to use the 2.7 Ecoboost was the Ford Edge Sport. That vehicle had some huge gains just for stage 1 that easily surpassed those seen for the F150 application of the 2.7 Ecoboost. While they are essentially the same engine there is one seemingly minor difference that actually makes a huge different when venturing into the quest for more power. If you read the detailed specs for the engine you will notice a difference under fuel delivery.
F150 – direct injection
Edge Sport – direct multi-shot injection
Tuners are pointing to the fuel delivery system as the reason why the gains are much higher for the Edge Sport.
Now the bad news. I assumed, given that they are corporate cousins, that the Fusion Sport would share all of the same engine specs as the Edge Sport (other than maybe a different final factory tune). The power ratings seemed to align with that. However, that is actually not the case as the Fusion Sport is not getting the direct multi-shot injection used on the Edge Sport (side note, the 3.0 Ecoboost MKZ will use direct multi-shot injection as well).
What does multi-shot do? I am unable to find a definitive answer other than some patents, etc. But it looks like it is able to inject fuel at “non-standard” times to help with emissions, detonation control, etc.
So I would expect F150 2.7 Ecoboost-like gains if you go the tuning route. The end of the world? No. But personally disappointing? Yes (for me at least).
One a final note. I am also stuck on why only use multi-shot on the 2.7 in the Edge Sport and nowhere else (F150, MKX, Fusion, etc.)?
